Intraperitoneal vitamin E and amniotic membrane treatment were both effective in the prevention of peritoneal adhesions. The combination of these agents did not produce a synergistic effect. Easy applicability of the intraperitoneal administration of vitamin E was its major advantage.

The association of fibrous dysplasia and intramuscular myxoma is a rare disease known as Mazabraud's syndrome. Both lesions tend to occur in the same anatomical region. The relationship between fibrous dysplasia and myxoma remains unclear, where an underlying localized error in tissue metabolism has been proposed to explain this occasional coexistence. Another example of this syndrome in a 52 year-old woman is reported. The patient presented with a soft tissue mass at the anteromedial mid part of the left thigh. After excision of the mass, three separate bone lesions were detected in her control MRI. The soft tissue mass was misdiagnosed as liposarcoma in another center, and the bone lesions were interpreted as metastasis. The hypocellularity and the indistinct vascular pattern of the lesion were consistent with myxoma. The Jam-Shidi needle biopsies of the osseous lesions were diagnosed as fibrous dysplasia. The recognition of this entity is important for appropriate management of the patient. Patients with soft tissue myxomas should be thoroughly examined for fibrous dysplasia. The greater risk of sarcomatous transformation in fibrous dysplasia with Mazabraud's syndrome should also be kept in mind.

The metal-related complications caused by orthopedic implants have long been a concern, but these problems have been considered mostly in the field of arthroplasty or internal fixation of fractures. The recent prevalence of spinal instrumentation has evoked a similar concern among spine surgeons. Here, we present a case of intraspinal metallosis adjacent to the pedicular hook occurring after treatment of vertebral fracture by posterior spinal instrumentation and fusion, and causing paraparesis at the 3rd postoperative year. Metallic granulomas can appear around the pedicular hooks as in the reported case. Crevice and fretting corrosion are results at the junctions of rod-screw, rod-hook, transverse connector rod and other connector rods in modular spinal implants. Adequate usage of transpedicular screws may inhibit the occurrence of such a complication. For this reason, further studies are necessary to increase metallic corrosive resistance to inhibit crevice and fretting corrosion.
